The bias generation circuit includes a linear regulator, a charge pump and a synchronous dual mode boost DC-DC converter. The linear regulator and the charge pump are coupled to the display panel respectively. The synchronous dual mode boost DC-DC converter is selectively operated in a pulse width modulation mode or a pulse frequency modulation mode according to a control signal. In the pulse width modulation mode, the synchronous dual mode boost DC-DC converter controls the linear regulator to generate a first voltage signal to the display panel. In the pulse frequency modulation mode, the synchronous dual mode boost DC-DC converter controls the charge pump to generate a second voltage signal to the display panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bias generation circuit and synchronous dual mode boost DC-DC converter therof","description":"A bias generation circuit coupled to a display panel is disclosed.
